I think i've got everything he's ever written/produced on my old PC and probably decided at some point I couldn't learn much from him as I never transferred most of his stuff to my new PC, although I must admit he did talk a lot of sense and some of his theories he spoke about where actually against the mainstream thinking in game and exactly in line with my own experiences which I liked.
One example was that mystery always spoke about hitting the girl with 'attraction material' first (before comfort). I always noticed that lots of the time, this was actually sucide, and 'negging' a girl for example, even playfully, early in the interaction used to backfire hard. That's when I heard Jon Sinn say about how he believed that actually comfort needed to come first and if nothing else it got me away from doing too much weird **** (negs and DHV stories etc) before the girl was actually comfortable in my presence and talking back etc. He said 'telling a girl 'we're not gonna get along' as an attraction builder/disqualifier when she doesn't even want to know you, isn't gonna work!' lol. Again, I agreed. Goes against lots of what you heard in the community at the time.
Another example was what he calls 'polite response' which again is something I noticed when approaching. There was this idea in the community that if she's talking back and qualifying to you, then she's attracted and it's on, but that's just not the case and some girls will be super chatty and qualify and everything else and even agreeing to 'sex talk' etc, but there will be a hard line where they will 100% reject compliance. The attraction isn't there. And it's not in your control. Guys in the community would always try to 'solve' what went wrong kinda thing but would ignore the fact that some girls are just polite and super social and friendly, but she might not be attracted and will probably never be attracted to you lol. He was one of the only one's who spoke about it
I'm sure there was a lot more things that he wrote about in regards to things i'd noticed from my own field reports that only he'd touched upon so I think he's knows some stuff.
I don't know what he's up too nowadays. His infields that I did saw always seemed kinda unnatural in that he was clearly following scrtips and stuff in his head (routines and stories etc) although i gather he moved away from the whole mystery method stuff and not really sure where he settled
Having said that, there simply isn't a PUA in existance who has ever especially amazed me who can do anything that i don't think I can.
It's mostly built on a massive lie. The level of 'game' needed when you open a girl who happens to like you and is attracted to you isn't anyhing special and not much to brag about
And if you you open a girl who very clearly isn't attracted to you no matter how 'good' you are, your game will be powerless, whether you are jon sinn or tyler or whoever else. Watching infields with a keen eye will tell you all you need to know about what's possible and what's not.
